Please someone help me! i worked so hard on this and i dont want to lose it!!!!!!!

I'm not really experienced at all with Forge, but I'm going to try to help

 

Did you try it in Eclipse(success) and then exported it(fail) once? If you did, test it in Eclipse again, you may have accidently removed the method before exporting it. Unlikely(because I wouldn't know how it would successfully compile and export), but possible.

src code pls. seems to have something to do with your sword.

How did you build your jar?  gradlew build?  Looks to me like it might be a (de)obfuscation problem, which can happen if you don't build your jar properly, i.e. your code tries to call a deobfuscated vanilla method, which doesn't exist when you put your jar into the minecraft mods folder since the vanilla code is obfuscated there.  Just a guess.

Heres the src for my sword:

 

package com.novacraft;

 

import net.minecraft.item.ItemSword;

 

public class NovaSword extends ItemSword {

 

public NovaSword(ToolMaterial p_i45356_1_) {

super(p_i45356_1_);

setTextureName(Novacraft.MODID + ":" + "novasword");

}

 

}

i just exported my mod as a JAR file thats it so idk whats going on

You need to build your mod using the gradlew build. Exporting it from eclipse will not work, because your mod needs to be reobfuscated to work in normal Minecraft. Once you ran this command, your jar will be in build/libs.

 

Well i did that and its not working. It says that the build failed because it could not copy mcmod.info What is that?

"setTextureName(Novacraft.MODID + ":" + "novasword");"

This is your problem. Take a closer look at it!

Why do you insist on being generally unhelpful and arrogant?

 

@ckazakeich, what Kriki98 should have told you is that the method is called

setBlockTextureName

.

Would it be

setItemTextureName

? Since it is a sword it would be an item.

Thankyou, but nothing has worked. I didnt try setBlockTexture because you know, swords are items lol. Any other suggestions?

diesieben07 gave you the answer.

 

The others are reasons it might or might not work properly, not why it won't run.

 

It shouldn't care if you dont' have a "mcmod.info" file.  But if it thinks you need it lookup up how to make one and put it in the appropriate folder.

 

This is all releted to how you setup your folder structure, eclipse environement, and how you are compiling the mod. 

 

Look up some tutorials on it.  The material from Wuppy are always a great help.

Why do you insist on being generally unhelpful and arrogant?

I shouldn`t tell him to use .setBlocTextureName. That will cause problems.

Just trying to help him don't know whats wrong in that.

No, you're right, setBlockTextureName was a silly suggestion of me.

 

My apologies.
